Portal Admins get error trying to change bookmarks for themselves

Well when I am logged into the portal, I try to go to 'content' to add a bookmark for my account and I get the attached error. It worked fine a few minutes ago. Had another SuperAdmin/Portal Admin try it and he got the same error, but it seems as though our standard employee accounts work fine. I went to logan.log and it reads as follows:

[Wed May 22 09:57:23 2013] xauthen REMOTE_USER="%myusername%" QUERY_STRING="ADMIN=TRUE"
[Wed May 22 09:57:23 2013] xauthen Bookmark 000000000000014 - parent can't be same value

Any ideas what is causing this?
